In common with most glaciers in Svalbard, VSF is polythermal (Schytt, 1964; Palosuo, 1987). VSF was the target of a re-cent International Polar Year (IPY) project (Pohjola et al., Vestfonna is an ice cap located on the western part of the Svalbard archipelago and covers an area of about 2,500 square kilometres. Jostedalsbreen Situated in Vestland county in Fjord Norway, Jostedalsbreen is the largest glacier in continental Europe , covering 487 square kilometres with ice up to 600 metres thick. During IPY4-Kinnvika an Automatic Weather Station (AWS) was installed on the western margin of the Vestfonna Ice Cap, Svalbard by a group from the Department of Earth Sciences, Uppsala University, Sweden. We analysed a 34-year data record of multi-spectral satellite imagery in order to study changes in glacier frontal positions of the ice cap Vestfonna. A consistent pattern of almost steady retreat of the southern and north-eastern outlet glaciers of the ice cap is observed while Franklinbreen, the only major outlet glacier draining towards the north-west shows re-advance. For Vestfonna, this amount is assumed to reach 90% of the accumulation sum of the preceding winter season 13, i.e.
The surface area of Austfonna is 8100 qkm. Understanding the response of fast flowing ice streams or outlet glaciers to changing climate is crucial in order to make reliable projections of sea level change over the coming decades.

Vestfonna is an ice cap located on the western part Nordaustlandet in the Svalbard archipelago in Norway. The glacier covers an area of about 2,500… Vestfonna The role of snowdrift on Vestfonna Ice Cap (Svalbard) In high Arctic regions, redistribution of snow mass by wind drift impacts the mass balance of glaciers. Particularly along the margin of larger ice caps, persistent katabatic winds become often strong enough to effectively remove snow from the surface and re-accumulate the eroded snow mass within the surrounding areas. Nordaustlandet (Nordöstlandet) är den näst största ön inom ögruppen Svalbard, med en yta av 14,443 km². Som namnet antyder ligger den nordost om Spetsbergen. En stor del av Nordaustlandet är täckt av glaciärer.
